About International Klein Blue

International Klein Blue (IKB), designated as #032AA1 in the hexadecimal color system, is a deep, vivid blue hue first mixed by the French artist Yves Klein. Klein patented this specific ultramarine shade to preserve its unique visual impact, aiming to capture the purest expression of blue. IKB is renowned for its intense saturation and almost velvety appearance, which results from its matte finish. The color evokes feelings of depth, infinity, and spirituality, reflecting Klein's artistic vision. Its distinctive character has made it a popular choice in art, design, and fashion, often used to make bold statements and create visually striking effects. IKB stands out due to its ability to captivate viewers and create a sense of immersion.

The hex color #032aa1, also known as International Klein Blue (IKB), presents considerable accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value (very dark blue) results in poor contrast against typical light-colored backgrounds, such as white or light gray. According to WCAG guidelines, sufficient contrast is essential for readability and usability. Therefore, using #032aa1 for text or interactive elements against a light background would fail to meet accessibility standards. To ensure accessibility, it's crucial to pair IKB with very light colors that provide a high contrast ratio (at least 4.5:1 for normal text and 3:1 for large text). White (#ffffff) or very light yellow (#ffffe0) could be potential candidates, but thorough testing with accessibility tools is necessary. Furthermore, avoid using IKB to convey critical information without additional cues, such as icons or labels, to benefit users who might not perceive the color accurately. Remember to consider users with color blindness when making design decisions involving IKB.
